openssl: makefile: set PWD if -config is used
openssl: makefile: set PWD if -config is used

When make is run using -C, $PWD is set to the current working directory.
It causes openssl to have a mismatch $dir (which is set to $ENV::PWD).

Make sure $PWD is set to the current working directory (using make
variable $(CURDIR)) when openssl is invoked with -config.
